Page 9: Removing Your Old Thermostat
Removing Your Old Thermostat Turn off your HVAC system WARNING: For your safety, you must turn off your HVAC system before removing your old thermostat. Every HVAC system is different, but usually you turn off a master switch or switch the system off in your home’s breaker [Figure 1.1] box. - Page 10 REMOVING YOUR OLD THERMOSTAT (CONT.) Remove your old thermostat Remove your old thermostat from the wall. Every thermostat is different, but usually you will need to push a tab on the [Figure 1.2] edge of the thermostat and separate the thermostat from the backplate. Note: Only remove the old thermostat.
- Page 11 REMOVING YOUR OLD THERMOSTAT (CONT.) Check for compatibility Inspect the wires leading into the backplate. If you find thick wires with wire nuts, or if the voltage of your HVAC system is 120V or higher, then your system [Figure 1.3] is not compatible with this smart thermostat.
